Party-goer: What are you doing?
George: What?
Party-goer: Did... did you just double dip that chip?
George: Scuze-me?
Party-goer: YOU DOUBLE DIPPED THE CHIP!
George: Double dipped? Wha-what are you talkin about?
Party-goer: You dipped the chip, you took a bite... and you dipped again!
George: So?
Party-goer: THAT'S LIKE PUTTING YOUR WHOLE MOUTH RIGHT IN THE DIP! Look, from now on when you take a chip, just take one dip and END IT!

1. When you dip something like a chip into a dip such as salsa, take a bite but don't eat the whole chip, then dip the same saliva-infested chip into the dip and eat it. Wanna never get invited back to that person's place or party? This is one of the quickest and most effective ways to do so.

2. When you have sex twice over a short period of time. Normally this refers to having sex with someone the morning after you had a drunken hook up the night before, but this can also refer to having sex with two different people in the same night.

1. I wasn't thinking at all and George saw me double dip at his cocktail party. Needless to say it wasn't a good night.
